    Abstract: An endoscope system includes: a light source configured to emit a pulse light; an imager configured to capture an image on a frame by frame basis; a processor configured to: determine a first Duty target value representing a Duty ratio of the pulse light to make an image that is captured in a next imaging frame have intended brightness; based on a frequency of vocal cords, determine a light emission period at a time when the pulse light is emitted; based on the first duty target value and the light emission period, determine a pulse width of the pulse light that is emitted next; and based on the light emission period and the pulse width, control the light source in light emission.

    Abstract: A communication system includes: a first signal line; a second signal line; a first signal line selection portion and a second signal line selection portion for selecting either one of the first signal line and the second signal line so as to be effective as the serial data; and a signal control portion for outputting a signal direction switching signal for controlling a selecting operation. The first signal line selection portion includes a first OR circuit and a first three-state buffer circuit provided on the first signal line, and a first buffer provided on the second signal line, and the second signal line selection portion includes a second OR circuit and a second three-state buffer circuit provided on the second signal line, a second buffer provided on the first signal line, and an inverter circuit provided between a terminal of the signal control portion and the second OR circuit.

    Abstract: A medical image processing device includes a processor configured to: obtain image data; generate, based on the obtained image data, a captured image including color component signals including a red component signal representing a red component, a green component signal representing a green component, and a blue component signal representing a blue component; calculate an intensity ratio between a fluorescent component signal and a reflected light component signal in a pixel of the captured image; determine, based on the calculated intensity ratio in the pixel of the captured image, a fluorescence region and a background region in the captured image; and generate a fluorescence image by performing, based on a result of the determination, image processing with parameters different from each other for color component signals in pixels positioned in the fluorescence region and color component signals in pixels positioned in the background region.
